Good design can provoke emotions. And that’s exactly what you need to do, if you’re going to change people’s behaviour around savings and pensions. Logic is not enough.
Stay away from standard stock photos. Find graphics which provoke strong reactions in your readers. Make them laugh, excite them, get them thinking about the kind of life they want to lead.
The colours you use will influence their emotions, too. Are you going for calm, pale and understated colours? Or dark and stormy? A good designer will make sure that your design re-enforces your key messages.
